BOSTON – In preparation for the upcoming 250th anniversary of the Battle of Bunker Hill, June 17, 1775, the National Parks of Boston is continuing its preservation efforts of the Bunker Hill Monument. Starting July 31, 2023, the Monument will undergo work on its pyramidion, the equally-sided pyramid that tops the obelisk.

The pyramidion suffers from sustained exposure to the elements, causing leaks that have broken down mortar, deteriorated masonry, and caused slippery conditions in the stairway of the interior of the Monument. During this project, workers will replace the mortar on the pyramidion roof and on the upper levels of the Monument in order to prevent additional and possibly irreparable damage.

In order to preserve this 180 year-old Monument, restoration work occurs every 20-30 years. The National Parks of Boston takes this preservation work seriously to ensure generations to come will continue to appreciate the Monument, honor the soldiers who fought and died on this battlefield, and consider the ongoing legacy of both the battle and the Monument.

This restoration project will cause considerable changes in public access to the Bunker Hill Monument. Starting July 31, fencing will go up on the Monument grounds to prepare for the installation of scaffolding. This fencing perimeter will establish the construction zone and will remain in place until the project's completion. The National Parks of Boston plans to keep the Monument open as often as possible during this project, while also recognizing that construction and restoration work may cause the Monument to close without notice.

Please note, the view from the Monument observatory windows will be obstructed due to scaffolding and scrim. Visitors can view live footage from the top of the Bunker Hill Monument by visiting Views of the Revolution: 360 Monument Webcams.

The work is expected to occur through the end of 2023. The Bunker Hill Museum will keep regular hours during this project.
